3 Description
The TPS3762 is a 65 V input voltage supervisor
with 4 μA IDD, 0.8% accuracy, fast detection time,
and a Built-In Self-Test feature. This device can be
connected directly to 12 V / 24 V industrial SELV
power rails for continuous monitoring of overvoltage
(OV) or undervoltage (UV) conditions; with its internal
resistor divider, TPS3762 offers the smallest total
solution size. Wide hysteresis voltage options are
available to ignore large voltage transients. Built-in
hysteresis on the SENSE pin prevents false reset
signals when monitoring a supply voltage rail.
The separate VDD and SENSE pins allow
redundancy sought by high-reliability systems and
SENSE can monitor higher and lower voltages than
VDD. Optional use of external resistors are supported
by the high impedance input of the SENSE pin. CTS
and CTR pins allow delay adjustability on the rising
and falling edges of the RESET signal. The CTS
functions as a debouncer by ignoring voltage glitches
on the monitored voltage rails.
The TPS3762 is available in a 2.9 mm × 1.6 mm
SOT23 8-pin package. TPS3762 operates over -40°C
to +125°C TA.
